I am building a solar carport and, unfortunately, my plans have been a work in progress the last two weeks. Being it is located at a school, I have to get my underground conduit installed in a hurry. I want to drop in some christy boxes and stub the conduit up until I know exactly where it needs to go. My question is how do I size them for 4(4") conduits?
